In the context of movement of cells, exocytosis is the process by which:

Show answer & explanation

Correct answer: C

Explanation

The correct answer is optin 3 i.e. cells move waste materials from within the cell into the extracellular fluid.

Explanation:

  • Exocytosis is a biological process in which a cell expels substances such as waste, hormones, or enzymes from its interior into the extracellular space.

  • It involves membrane-bound vesicles (small sacs) that fuse with the cell membrane, releasing their contents outside the cell.

  • This process is essential for waste removal, cell signaling, and secretion of important molecules.

  • Exocytosis is the reverse of endocytosis, where substances are taken into the cell.

  • It plays a crucial role in various physiological processes such as neurotransmitter release, hormone secretion, and membrane recycling.

  • Without exocytosis, cells would accumulate waste and be unable to communicate effectively with their environment.
